摘要
阐述了低应变反射波法的基本理论,以精伊霍铁路桩基工程实测低应变时域反射波形为实例,详细分析了基桩各种缺陷引起低应变时域反射波形态特征发生变化的内在联系,论证各种基桩异常及缺陷在低应变时域反射波形上反映的特征。
The basic theory of low strain reflective wave method is expatiated, taking the slow strain time domain backscatler wave shape of the pile foundation engineering of Jing-Yi-Huo railway as an example, the internal relations of changes of mor- phological characteristics of the time domain backscatler wave shape caused by the different kinds of defect of the foundation pile are analyzed, the morphological characteristics of slow strain time domain backscatler wave shape reflected by all sorts of abnormity and defect of the foundation pile are demonstrated.
